An analysis of ${B}^{0}\ensuremath{\rightarrow}D{K}^{*0}$ decays is presented, where $D$ represents an admixture of ${D}^{0}$ and ${\overline{D}}^{0}$ mesons reconstructed in four separate final states: ${K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$, ${\ensuremath{\pi}}^{\ensuremath{-}}{K}^{+}$, ${K}^{+}{K}^{\ensuremath{-}}$ and ${\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$. The data sample corresponds to $3.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of proton-proton collision, collected by the …

The difference in the angular distributions between beauty quarks and antiquarks, referred to as the charge asymmetry, is measured for the first time in $b\overline{b}$ pair production at a hadron collider. The data used correspond to an integrated luminosity of $1.0\text{ }\text{ …

The decays ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}_{s}^{+}$ and ${B}_{c}^{+}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}_{s}^{*+}$ are observed for the first time using a dataset, corresponding to an integrated luminosity of $3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected by the LHCb experiment in proton-proton collisions at center-of-mass energies of $\sqrt{s}=7$ and 8 TeV. The statistical significance …
